47.4.1. Analysis with 100k Source Resistance

Try these first

1. 1.

   What is the desired voltage gain for a Common Collector amplifier?

   Hint

   Think about the purpose of such an amplifier.

2. 2.

   Define input and output impedance in the context of amplifiers.

   Hint

   Remember their roles in amplifier circuits.

3. 3.

   What is a desired characteristic of Common Collector amplifiers?

   • High voltage gain
   • Input impedance high
   • Output impedance high

   Hint

   Refer to the properties of CC amplifiers.

4. 4.

   True or False: The upper cutoff frequency is determined primarily by the load capacitance.

   • True
   • False

   Hint

   Think about what affects the frequency response of an amplifier.

5. 5.

   A Common Collector amplifier has a load of 50 kΩ and a source resistance of 50 kΩ. Calculate the voltage gain and comment on the effectiveness of the design based on the results.

   Hint

   Use impedance formulas to derive conclusions.

6. 6.

   In a practical amplifier, the source resistance fluctuates due to external factors, analyze how this would impact the upper cutoff frequency dramatically.

   Hint

   Consider how input and output resistances interact dynamically.
